Abstract

"PROCESSO PARA A PRODUçãO DE MICROCáPSULAS CONTENDO UM MATERIAL AQUOSO DENTRO DE UMA ESTRUTURA POLIMéRICA, MICROCáPSULAS, SUSPENSãO DE MICROCáPSULAS EM UM LìQUIDO ORGâNICO, E, FORMULAçãO PESTICIDA EMPACOTADA". Uma suspensão de microcápsulas em um líquido orgânico, as microcápsulas contendo uma fase aquosa, é produzida mediante a polimerização interfacial na presença de um catalisador de transferência de próton de uma emulsão de água em óleo, em que a fase aquosa contém um pré-polímero de uréia/formaldeído ou melamina/formadeído."PROCESS FOR THE PRODUCTION OF MICROCapsules CONTAINING A WATERFUL MATERIAL WITHIN A POLYMERIC STRUCTURE, MICROCapsules, SUSPENSION OF MICROCapsules IN AN ORGANIC LIQUID, AND, PACKED PESTICIDE FORMULATION". A suspension of microcapsules in an organic liquid, microcapsules containing an aqueous phase, is produced by interfacial polymerization in the presence of a proton transfer catalyst from a water-in-oil emulsion, in which the aqueous phase contains a prepolymer of urea / formaldehyde or melamine / formadehyde.
